How to Replace a Recliner Actuator
Replacing a recliner actuator is a more involved repair than swapping a power supply or handset, but it can be completed at home with basic tools. The most important step is measuring and matching the correct specifications before ordering. An incorrect actuator will not fit or will prevent the chair from operating correctly. If you are unsure which motor system is fitted, start with our recliner motor system identification guide.
Safety First
- Disconnect the power supply from the wall outlet before starting.
- Do not remove the actuator while the chair is loaded or in an unstable position.
- Keep hands, feet and loose clothing away from the mechanism at all times.
- Do not force the mechanism manually while the actuator is connected.
- If the chair is stuck in a raised or extended position, contact CouchGuard before attempting removal.
Before You Start: Confirm the Actuator Is the Fault
Check the power supply, handset, cables and control box before replacing the actuator. An actuator replacement is only necessary if those components have been confirmed as working. Our electric recliner troubleshooting guide can help you work through the basic checks first.
- The motor hums but the chair does not move — possible jammed or seized actuator.
- Grinding or clicking during movement — worn internal gears or lead screw.
- Chair moves in one direction only — may be actuator, control box or handset.
- Chair moves slowly or stops mid-cycle — may be actuator friction, power supply or overload.
How to Choose the Correct Replacement Actuator
Record the following specifications from the existing actuator label and by measurement before ordering. If the connector is unfamiliar, compare it with our recliner connector and plug types guide.
- Brand and model number: Record the complete model number from the label.
- Stroke length: The distance the inner tube travels from fully retracted to fully extended, in millimetres. This is the most critical measurement.
- Overall retracted length: The total length of the actuator when fully retracted, measured from mounting hole to mounting hole.
- Force rating: The maximum load in Newtons or kilograms. Particularly important for lift chair actuators.
- Voltage: Usually 24V or 29V DC.
- Connector type: Photograph the connector and pin arrangement.
See our guide on how to read a recliner motor label for help interpreting these specifications.
What You Will Need
- Compatible replacement actuator
- Tape measure or ruler
- Flat-head screwdriver or pliers (for clevis pins)
- Phone or camera to photograph connections and mounting
- Torch for working under the chair
Step-by-Step: How to Replace the Actuator
- Disconnect the power supply from the wall outlet and wait a few seconds.
- Photograph the actuator in position — both ends, the cable routing and the mounting brackets.
- Disconnect the actuator cable from the control box by gripping the connector body and pulling straight out.
- Release the mounting pins: most actuators are held at each end by a clevis pin and split pin or R-clip. Remove the split pin or R-clip first, then slide out the clevis pin. Keep all hardware for reuse or replacement.
- Remove the old actuator from the chair frame. Note the orientation and which end connects to the motor bracket and which to the mechanism linkage.
- Photograph the label on the old actuator before setting it aside.
- Compare the old and new actuators: confirm stroke length, overall length, connector type and mounting hole diameter match.
- Fit the new actuator in the same orientation as the old one. Insert the clevis pins and secure with the split pins or R-clips.
- Connect the actuator cable to the control box. Push the connector firmly until it seats.
- Route the cable away from moving parts and pinch points.
- Reconnect the power supply to the wall outlet.
- Test the chair slowly through its full range of movement. Keep clear of the mechanism during testing.
After Replacement: What to Check
- The chair completes its full range of movement in both directions.
- No grinding, clicking or unusual noise during operation.
- The actuator cable does not catch or stretch during movement.
- The mounting pins are secure at both ends.
- The chair stops when the button is released.
Common Actuator Replacement Mistakes
- Wrong stroke length: An actuator with a different stroke length will prevent the chair from reaching its full range or cause the mechanism to over-extend.
- Wrong overall length: An actuator that is too long or too short will not fit the mounting points correctly.
- Wrong force rating: A lower-rated actuator in a lift chair may fail under load.
- Incorrect orientation: Fitting the actuator back-to-front will reverse the direction of movement.
- Unsecured mounting pins: Always refit the split pins or R-clips after inserting the clevis pins.
- Cable through moving parts: Route the cable away from all hinges and linkages.
Contact CouchGuard
If you are unsure which actuator to order or need help identifying the correct specifications, call 1300 268 244 or email info@couchguard.com.au with photographs of the actuator label, both mounting ends, the connector and the chair mechanism. We can discuss compatibility and replacement-part availability.
Frequently Asked Questions
Do I need a technician to replace a recliner actuator?
Most recliner actuator replacements can be completed at home with basic tools. The key steps are measuring the stroke length and overall length correctly, matching the connector, and securing the mounting pins after fitting.
How do I measure the stroke length of my recliner actuator?
Disconnect the power and remove the actuator from the chair. Extend the inner tube manually to its full travel and measure the distance from the retracted position to the fully extended position. See our motor label guide for more detail.
Can I use an actuator with a different brand but the same stroke length?
Not automatically. The connector, force rating, voltage and overall length must also match. Send the label photograph and measurements to CouchGuard for a compatibility check.
My new actuator fits but the chair moves in the wrong direction. What is wrong?
The actuator may have been fitted in the wrong orientation. Remove it and refit with the motor end and mechanism end reversed.
